where is command line sopport?

The only argument you can pass to Splat.exe is:
/profile:"c:\full\path\to\<ProfileName>.profile"You can easily create a shortcut for a profile by right-clicking the profile name and choosing the "Send launch profile shortcut to desktop" entry. As the help file explains, launching a profile in this manner doesn't display the main interface. Only the tray icon is shown for the duration of the profile.

Sometimes it gets wacky like that. Choose
View > Reset splitter position from the menu and restart Splat.

I'm going to guess you're running a folder and expecting Splat to continue when you close Windows Explorer. As the info button near that option explains:
Enabling this option runs the item and waits, indefinitely, for its process ID (PID) to close before moving on to the next item. This option is typically used with console or commandline programs that exit on their own after running a command. Use with care.In other words, that option is not designed to do what you want with a folder. It's designed mainly for commandline apps.
suggest: add close/kill all programs or common templet profile(contain some always runing progames like, firewall antivirus...)
I've added a lot of profiles(10), If I want to switch to PURE game mode(game profile), maybe I need to close a lot of programs of other profiles for "PURE". Or someday, if I add another profile contain some new programs, then I need to edit all profiles for "PURE". 
work profile: close all (or recover to common templet profile)-> A.exe B.exe C.folder
surf profile: close all (or recover to common templet profile)-> C.folder F.exe
game profile: close all (or recover to common templet profile)-> G.exe-yjs14
No, I will not be adding a "close all" type of option or any sort of pre-made templates. The reason is that it's easy for you as a user to say to yourself, "Just close all running programs" because
you know what to close. For me, as the programmer, it's damn near impossible. Why? Consider all the stuff currently running in your task manager. I can't just go attempt to close down every running process in there. That would be Very Badâ„¢. Your computer would completely shit the bed if I tried that.
As an FYI, you can run a profile within a profile. So, if you add another profile called, say, NEWSTUFF, with a lot of, ahem, new stuff, you can simply add an entry in your PURE profile that calls this NEWSTUFF profile. You can get pretty modular with Splat in this way.
